United managed to bounce back from 2-0 down to beat West Ham 4-2 at Upton Park in the Premier League on Saturday.
“Obviously, it will be a very important game for us and again, an away game. I think we can be positive after the West Ham performance,” he said.
“We scored four goals and we played very good football and I think this is the way we have to play against Chelsea.
“The defending part, we need to improve a bit more, but we will be all right.”
